Date codes.

I have seen there are repeat codes by years. If I have, for example, a 10AN movement with a circle. How I know the year of the movement?

Best regards.

It comes down to stamping variations on the movement. The earlier version will tend to have a serial number and be Swiss, rather than USA, especially for these 1920s/30s movements.

If in doubt just ask and I'm sure we will be able to advise.
